3.5 mil years ago, summer temps were ~8°C warmer than today, CO2 was ~400 ppm

Two recent studies on past temperatures… Pliocene Warmth, Polar Amplification, and Stepped Pleistocene Cooling Recorded in NE Arctic Russia Understanding the evolution of Arctic polar climate from the protracted warmth of the middle Pliocene into the earliest glacial cycles in the Northern Hemisphere has been hindered by the lack of continuous, highly resolved Arctic time…

Why Climate Change Is Not an Environmental Issue


This video is to promote general awareness of the science of climate change. It was edited and narrated by @ryanlcooper, using illustrations from around the web. Find more of my stuff athttp://www.ryanlouiscooper.com. It was inspired largely by something David Roberts wrote: http://grist.org/article/2010-08-09-e… Find David at http://grist.org/author/david-roberts/ and @drgrist.

Arctic Ocean ‘acidifying rapidly’

BBC: The Arctic seas are being made rapidly more acidic by carbon-dioxide emissions, according to a new report. Scientists from the Arctic Monitoring and Assessment Programme (AMAP) monitored widespread changes in ocean chemistry in the region. They say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry to…

Atmospheric Oxygen


Dr. Ralph Keeling on atmospheric Oxygen and Carbon Dioxide. Ralph Keeling is the current program director of the Scripps CO2 Program. He is also a Professor and the Principal Investigator for the Atmospheric Oxygen Research Group at SIO.

Oxygen levels are decreasing globally due to fossil-fuel burning. The changes are too small to have an impact on human health, but are of interest to the study of climate change and carbon dioxide. These plots show the atmospheric O2 concentration relative to the level around 1985. The observed downward trend amounts to 19 ‘per meg’ per year. This corresponds to losing 19 O2 molecules out of every 1 million O2 molecules in the atmosphere each year. http://scrippso2.ucsd.edu/
